Pool Filter Cleaning & Replacement

Your Filter Works Harder Than You Think

Your pool filter is the hardest working piece of equipment you own. It runs for hours every single day, pushing thousands of gallons of water through sand, cartridges, or grids to trap dirt, debris, algae, and other contaminants. Over time, all that trapped material builds up inside your filter. When filters get clogged, they cannot do their job properly. Water stays cloudy, chemicals do not work as well, and your pump has to work harder, which can lead to expensive repairs.

Most pool owners never think about their filter until something goes wrong. But regular filter cleaning is just as important as balancing your chemicals or skimming leaves. Clean filters mean clear water, efficient equipment, and lower energy bills. Whether you have a sand filter, cartridge filter, or DE filter, we have the expertise and equipment to clean or replace it properly. We serve Paramount homeowners who want their pools running at peak performance year-round.

How We Clean Your Pool Filter

Different filter types need different cleaning approaches. We handle all three common types of pool filters with the proper techniques and equipment for each. Here is what we do:

• Cartridge filter cleaning involves removing cartridges, deep cleaning with professional solutions, and inspecting for tears or damage
• Sand filter maintenance includes backwashing to flush trapped debris and checking sand condition for replacement needs
• DE filter service means breaking down the filter, cleaning grids thoroughly, and recharging with fresh diatomaceous earth
• Pressure testing to ensure your filter operates at the correct PSI for maximum efficiency
• O-ring and gasket inspection to prevent leaks and maintain proper seals
• Tank inspection for cracks, corrosion, or other damage that could affect performance
• Complete reassembly with proper tightening and testing to confirm everything works correctly

We bring professional cleaning equipment and solutions that do a much better job than just spraying your cartridges with a garden hose. Our process removes oils, minerals, and deeply embedded debris that home cleaning misses. After we finish, your filter works like new again. Many customers combine filter cleaning with our weekly pool cleaning service to keep everything running perfectly.

When Your Filter Needs Replacement

Even with regular cleaning, filters do not last forever. Cartridges typically need replacement every 1 to 3 years depending on use and water quality. Sand should be replaced every 3 to 5 years as it breaks down and loses its filtering ability. DE grids last longer but eventually tear or wear out. We always inspect your filter components during cleaning and let you know if replacement makes more sense than another cleaning.

Signs you might need filter replacement include water that stays cloudy no matter what you do, consistently high filter pressure readings, visible tears or damage to cartridges or grids, sand that clumps together or has become smooth and round, and filters that need cleaning more frequently than normal. Sometimes you can replace just the media like cartridges or sand while keeping the existing tank. Other times, the entire filter system needs upgrading.

We carry quality replacement filters and parts for all major brands. We can handle the entire replacement process from helping you choose the right filter size for your pool to installing it properly and testing the system. If your filter is ancient and barely working, upgrading to a modern, efficient model can actually save you money on energy costs while giving you clearer water.

Filter Maintenance Schedule That Works

How often should you clean your filter? It depends on several factors including how much you use your pool, how many trees and plants surround it, and what type of filter you have. As a general rule, cartridge filters should be cleaned every 4 to 8 weeks during swimming season. Sand filters benefit from backwashing every 2 to 4 weeks. DE filters typically need service every 6 to 8 weeks.

The best indicator is your pressure gauge. When pressure rises 8 to 10 PSI above the normal clean pressure, your filter needs attention. We can set up a regular maintenance schedule based on your specific filter type and pool conditions. Many customers have us clean their filter 2 to 4 times per year to keep everything running smoothly. Regular maintenance is always cheaper than dealing with equipment failure or poor water quality down the road. We also offer equipment repair services if your filter or pump system needs more than just cleaning.
